我想创建动态菜单,循环数组为1个对象菜单。但是发生了错误。 我们的代码低于它:
$menus = [{"id" => 1, "label" => "content", "parent_id" => 0},{"id" => 2, "label" => "inbox", "id" => 3, "parent_id" => 0}, {"id" => 4, "label" => "item", "parent_id" => 0}];
$sub_menus = [{"id" => 5, "label" => "banner", "parent_id" => 1},{"id" => 6, "label" => "ads", "parent_id" => 1}];
foreach($menus as $row => $value){
$nav[$row] = $value;
foreach($sub_menus as $r => $v) {
if($v['parent_id'] == $value['id']){
$nav[$row]['sub_menu'][$r] = $v;
}
}
}
我收到错误通知,“间接修改App \ Menu的重载元素无效”
请帮帮我:)。

代码正在运行。您的阵列中有很多错误。
<强>固定强>:
$menus = [
[
"id" => 1,
"label" => "content",
"parent_id" => 0
],
[
"id" => 2,
"label" => "inbox",
"parent_id" => 0
],
[
"id" => 4,
"label" => "item",
"parent_id" => 0
]
];
$sub_menus = [
[
"id" => 5,
"label" => "banner",
"parent_id" => 1
],
[
"id" => 6,
"label" => "ads",
"parent_id" => 1
]
];
foreach($menus as $row => $value){
$nav[$row] = $value;
foreach($sub_menus as $r => $v) {
if($v['parent_id'] == $value['id']){
$nav[$row]['sub_menu'][$r] = $v;
}
}
}

你有一个破碎的数组,比如json到数组的错误转换;
你可以测试(执行)它here(工作示例)
